However, the above refrigerants are flammable and explosive. Under certain concentration conditions, if they come into contact with air and encounter open flames, they may cause combustion or even explosion. The relevant technology proposes a control method for an air conditioner. When the air conditioner is in operation and the leak detector detects that there is a flammable refrigerant leak in the surrounding area, the outdoor unit of the air conditioner is powered off, the control program of the air conditioner is locked, the air conditioner does not process the received instructions, the air conditioner displays a fault code and the buzzer alarms; the indoor fan motor of the air conditioner runs at a high gear, the ventilation motor starts, and the entire air conditioner is powered off after t2 time.

Summary of the invention

[0006] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below.

[0029] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0030] In the embodiments of the present disclosure, smart home appliances refer to home appliances that are formed by introducing microprocessors, sensor technology, and network communication technology into home appliances, and have the characteristics of intelligent control, intelligent perception, and intelligent application. The operation process of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet, and electronic chips. For example, smart home appliances can be connected to other smart home appliances to form a smart home system, and realize the linkage control and collaborative management of multiple smart home appliances. In the embodiments of the present disclosure, smart home appliances include smart air conditioners.

[0031] At present, due to the problem of refrigerant R22 damaging the ozone layer, more and more air conditioners are beginning to use more environmentally friendly refrigerants such as R32 and R290 to replace R22. However, the above refrigerants are flammable and explosive. Under certain concentration conditions, if they come into contact with air and encounter open flames, they may cause combustion or even explosion. The relevant technology proposes a control method for an air conditioner. When the air conditioner is in operation and the leak detector detects that there is a flammable refrigerant leak in the surrounding area, the outdoor unit of the air conditioner is powered off, the control program of the air conditioner is locked, the air conditioner does not process the received instructions, the air conditioner displays a fault code and the buzzer alarms; the indoor fan motor of the air conditioner runs at a high gear, the ventilation motor starts, and the entire air conditioner is powered off after t2 time.

[0032] The relevant technology only discharges the flammable refrigerant when it leaks. However, when other household appliances in the room fail or safety hazards are identified, the flammable refrigerant stored in the air conditioner also poses a risk and is prone to secondary damage, which is not conducive to the safety of users at home.

[0033] Combination Figure 1 As shown, an embodiment of the present disclosure provides an intelligent air conditioner, including: a compressor 10, an outdoor heat exchanger 20, a throttle valve 30 and an indoor heat exchanger 40. The compressor 10, the outdoor heat exchanger 20, the throttle valve 30 and the indoor heat exchanger 40 are connected in sequence through a refrigerant pipeline to form a refrigerant circulation loop.

[0034] Optionally, the intelligent air conditioner further includes an external fan 50 and an internal fan 60. The external fan 50 is arranged relative to the outdoor heat exchanger 20. The internal fan 60 is arranged relative to the indoor heat exchanger 40.

[0035] The smart air conditioner provided by the embodiment of the present disclosure can perform cooling, air supply or standby operation according to user needs, thereby ensuring the user experience.

[0036] Optionally, the smart air conditioner further includes a one-way valve 70. The one-way valve 70 is provided on the refrigerant pipeline between the outdoor heat exchanger 20 and the compressor 10 to limit the one-way flow of the refrigerant from the compressor 10 to the outdoor heat exchanger 20. This can prevent the flammable refrigerant from flowing back to the indoor side after the smart air conditioner executes the refrigerant transfer scheme, which is conducive to ensuring the safety of the smart air conditioner.

[0037] Combination Figure 2 As shown, the embodiment of the present disclosure provides a method for controlling an intelligent air conditioner, comprising:

[0038] S201, the processor determines a risk response plan for the smart air conditioner in response to a control instruction of the safety linkage mode.

[0039] S202, when the risk response plan is the refrigerant transfer plan, the processor controls the intelligent air conditioner to operate in cooling mode and controls the throttle valve to close.

[0040] S203, the processor controls the compressor, the indoor fan and the outdoor fan to run for a preset time and then shut down to transfer the refrigerant from the indoor side to the outdoor side.

[0041] Using the method for controlling the smart air conditioner provided by the embodiment of the present disclosure, when the smart air conditioner receives the control instruction of the safety linkage mode, the specific risk response plan is first determined to control the smart air conditioner to make adaptive adjustments to reasonably avoid risks. And when the risk response plan is the refrigerant transfer plan, the smart air conditioner operates in the cooling mode and closes the throttle valve to cut off the path of the flammable refrigerant flowing from the outdoor side to the indoor side. Then the compressor, the indoor fan and the outdoor fan are shut down after running for a preset period of time, so that the flammable refrigerant can be gradually transferred from the indoor side to the outdoor side through the refrigerant pipeline. As a result, the embodiment of the present disclosure can discharge the flammable refrigerant stored in the indoor unit of the smart air conditioner to the outdoor side in advance when there is a safety hazard indoors, so as to assist the smart air conditioner to avoid secondary damage before the indoor danger expands, which is beneficial to ensuring the safety of users at home.

[0042] In the disclosed embodiments, the safety linkage mode refers to a centralized protection mode under the smart home system. The smart home system can link multiple smart home appliances in the room to achieve linkage control and collaborative management of multiple smart home appliances. When a smart home appliance fails or identifies a safety hazard, the safety linkage mode of the smart home system will be triggered, and the corresponding control instructions will be sent to other smart home appliances, so that they can respond in advance to avoid secondary damage, which is conducive to reducing indoor risks.

[0043] Optionally, the processor controls the throttle valve to close, including: the processor determines the target closing rate of the throttle valve according to the safety linkage mode; the processor controls the throttle valve to close according to the target closing rate. In this way, the disclosed embodiment can reasonably set the target closing rate of the throttle valve in combination with the safety linkage mode, ensuring that it can complete the transfer of the indoor flammable refrigerant before the indoor danger expands, and can reduce the adverse effects of too fast closing of the valve on the smart air conditioner.

[0044] Optionally, the processor determines the target closing rate of the throttle valve according to the safety linkage mode, including: the processor determines the target closing rate of the throttle valve according to the triggering object and / or triggering reason of the safety linkage mode. In this way, the disclosed embodiment can judge the triggering object and / or triggering reason of the safety linkage mode, and then analyze its degree of association with the smart air conditioner or the degree of harm to the smart air conditioner, so as to set the target closing rate of the throttle valve more reasonably, ensure that it can complete the transfer of the indoor flammable refrigerant before the indoor danger expands, and reduce the adverse effects of too fast valve closing on the smart air conditioner.

[0045] Optionally, after the processor controls the intelligent air conditioner to operate in cooling mode and controls the throttle valve to close, it also includes: the processor controls the compressor to operate at high frequency; and / or the processor controls the internal fan to operate at high wind speed; and / or the processor controls the external fan to operate at high wind speed. In this way, after the embodiment of the present disclosure controls the intelligent air conditioner to operate in cooling mode, it further controls the compressor to operate at high frequency, and / or the internal fan to operate at high wind speed, and / or the external fan to operate at high wind speed. Thereby, the discharge speed of the flammable refrigerant from the indoor side to the outdoor side can be accelerated, further ensuring that the intelligent air conditioner can complete the transfer of the flammable refrigerant before the indoor danger expands, which is conducive to timely avoidance of secondary damage.

[0046] Optionally, the processor controls the high-frequency operation of the compressor, including: the processor determines the target operating frequency and target frequency-limiting current of the smart air conditioner; the processor controls the compressor to operate at the target operating frequency, and detects the real-time working current of the smart air conditioner at the target operating frequency; the processor adjusts the operating frequency of the compressor according to the real-time working current and the target frequency-limiting current. In this way, the embodiment of the present disclosure can first control the compressor to operate at a higher target operating frequency, then detect the real-time working current at the target operating frequency, and compare the magnitude relationship between the real-time working current and the target frequency-limiting current, and then reasonably adjust the operating frequency of the compressor so that it can more safely execute the refrigerant transfer scheme.

[0047] Optionally, the processor determines the target operating frequency and target frequency-limited current of the smart air conditioner, including: the processor determines the target operating frequency and target frequency-limited current of the smart air conditioner according to the safety linkage mode. In this way, the disclosed embodiment can reasonably set the target operating frequency and target frequency-limited current of the smart air conditioner in combination with the safety linkage mode, and while controlling the high-frequency operation of the compressor to speed up the transfer speed of the flammable refrigerant, it can also ensure the safety of the smart air conditioner when executing the refrigerant transfer solution.

[0048] Furthermore, the processor may determine the target operating frequency and target frequency-limited current of the smart air conditioner according to the triggering object and / or triggering cause of the safety linkage mode. Specifically, in some embodiments, the two can be set in a one-to-one correspondence by establishing a preset association relationship, such as matching the target operating frequency of the corresponding smart air conditioner according to the triggering object of the safety linkage mode, and matching the target frequency-limited current of the corresponding smart air conditioner according to the triggering cause of the safety linkage mode. In other embodiments, the two may not be set in a one-to-one correspondence, but are determined through comprehensive analysis, and the embodiments of the present disclosure do not make specific limitations on this. Therefore, the embodiments of the present disclosure can analyze the triggering object and triggering cause of the safety linkage mode, the degree of association with the smart air conditioner, or the degree of harm to the smart air conditioner, so that the target operating frequency and target frequency-limited current of the smart air conditioner can be set more reasonably to improve the safety of the smart air conditioner when executing the refrigerant transfer solution.

[0049] Optionally, the processor adjusts the operating frequency of the compressor according to the real-time operating current and the target frequency-limiting current, including: when the real-time operating current is greater than the target frequency-limiting current, the processor reduces the operating frequency of the compressor; the processor detects the new real-time operating current of the intelligent air conditioner after the operating frequency is reduced; when the new real-time operating current is less than or equal to the target frequency-limiting current, the processor maintains the operating frequency of the compressor. In this way, the embodiment of the present disclosure can first control the compressor to operate at a higher target operating frequency, and then detect the real-time operating current at the target operating frequency. When the real-time operating current is greater than the target frequency-limiting current, it indicates that the operating frequency of the compressor at this time is too high, and there may be certain safety issues when the intelligent air conditioner executes the refrigerant transfer scheme in this state. Therefore, the processor appropriately reduces the operating frequency of the compressor and re-detects its corresponding real-time operating current until the new real-time operating current is less than or equal to the target frequency-limiting current. At this time, the execution of the refrigerant transfer scheme is not likely to cause safety issues for the intelligent air conditioner. Therefore, the embodiment of the present disclosure can control the high-frequency operation of the compressor to speed up the transfer speed of the flammable refrigerant while also ensuring the safety of the intelligent air conditioner when executing the refrigerant transfer scheme.

[0050] Optionally, the processor determines the risk response plan of the smart air conditioner, including: the processor determines the risk warning level of the smart air conditioner according to the safety linkage mode; the processor determines the risk response plan of the smart air conditioner according to the risk warning level of the smart air conditioner. In this way, the embodiment of the present disclosure can analyze the risk level corresponding to the safety linkage mode, and then determine the risk warning level of the smart air conditioner, and determine the risk response plan corresponding to the smart air conditioner accordingly, so as to help control the smart air conditioner to make adaptive adjustments to reasonably avoid risks.

[0051] Optionally, the processor determines the risk warning level of the smart air conditioner according to the safety linkage mode, including: the processor determines the risk warning level of the smart air conditioner according to the triggering object and / or triggering reason of the safety linkage mode. In this way, the embodiment of the present disclosure can determine the triggering object and / or triggering reason of the safety linkage mode, and then analyze its risk level relative to the smart air conditioner, so as to determine the risk warning level of the smart air conditioner at this time, so as to control the smart air conditioner to make adaptive adjustments and reasonably avoid risks.

[0052] Specifically, in some embodiments, when the triggering cause of the safety linkage mode is the tripping of other smart home appliance circuit breakers, the risk warning level of the smart air conditioner is determined to be a primary risk warning. In other embodiments, when the triggering cause of the safety linkage mode is a smoke alarm, the risk warning level of the smart air conditioner is determined to be an intermediate risk warning. In other embodiments, when the triggering cause of the safety linkage mode is a fire alarm, the risk warning level of the smart air conditioner is determined to be an advanced risk warning. Therefore, the embodiments of the present disclosure can reasonably determine the corresponding risk warning level of the smart air conditioner in combination with the triggering cause of the safety linkage mode, which is conducive to the smart air conditioner to execute appropriate risk response plans and thus reasonably avoid risks.

[0053] Optionally, the disclosed embodiment may also set more risk warning levels, which are not limited to the above three risk warning levels. The risk warning level may also be reasonably set according to the triggering objects and / or triggering reasons of more safety linkage modes to accurately divide the risk level relative to the smart air conditioner, which are not listed here one by one. At the same time, based on the above multiple risk warning levels, the smart air conditioner can set corresponding risk response plans and make corresponding functional adjustments to reasonably avoid risks.

[0054] Optionally, the processor determines the risk response plan of the smart air conditioner according to the risk warning level of the smart air conditioner, including: when the risk warning level of the smart air conditioner is a primary risk warning, the processor determines that the risk response plan of the smart air conditioner is a power-off protection plan; or, when the risk warning level of the smart air conditioner is a medium risk warning, the processor determines that the risk response plan of the smart air conditioner is a refrigerant transfer plan; or, when the risk warning level of the smart air conditioner is a high risk warning, the processor determines that the risk response plan of the smart air conditioner is a refrigerant isolation plan. In this way, the embodiment of the present disclosure can set an adaptive risk response plan for different risk warning levels, so as to help control the smart air conditioner to make adaptive adjustments to reasonably avoid risks. When the risk warning level is a primary risk warning, it indicates that the current dangerous situation is difficult to affect the smart air conditioner, or the degree of harm to the smart air conditioner is low, and the smart air conditioner is relatively safe at this time. Therefore, the embodiment of the present disclosure determines that the risk response plan of the smart air conditioner at this time is a power-off protection plan, and the smart air conditioner is promptly powered off, which is conducive to avoiding subsequent risks. When the risk warning level is a medium risk warning, it indicates that the current dangerous situation may gradually expand and be transmitted to the smart air conditioner, and then cause a certain degree of secondary damage to the smart air conditioner. At this time, the smart air conditioner is at considerable risk. Therefore, the embodiment of the present disclosure determines that the risk response plan for the smart air conditioner at this time is a refrigerant transfer plan. By discharging the flammable refrigerant stored in the smart air conditioner indoor unit to the outdoor side in advance, it can assist the smart air conditioner to avoid secondary damage before the indoor dangerous situation expands, which is beneficial to ensure the safety of users at home. When the risk warning level is a high-level risk warning, it indicates that the current dangerous situation is very likely to have spread to the smart air conditioner and is about to cause more serious secondary damage. Therefore, the embodiment of the present disclosure determines that the risk response plan for the smart air conditioner at this time is a refrigerant isolation plan. By quickly isolating the indoor refrigerant and the outdoor refrigerant, the degree of damage to the smart air conditioner can be reduced, which is beneficial to avoid further expansion of the dangerous situation.

[0055] Specifically, in some embodiments, the processor responds to the control instruction of the safety linkage mode, and further analyzes the safety linkage mode to determine its triggering object and triggering reason. For example, when the triggering object is identified as a smart range hood, and the triggering reason is a smoke detection alarm, the processor determines that the degree of harm to the smart air conditioner is relatively high, and there is a possibility of indoor fire, which may cause the smart air conditioner to burn combustible refrigerant or even explode. At this time, it is determined that the safety linkage mode belongs to the intermediate safety mode, and the smart air conditioner needs to execute the refrigerant transfer plan within a limited time to reasonably avoid risks.

[0056] To this end, the processor controls the intelligent air conditioner to operate in cooling mode, and controls the throttle valve to close at a speed of 20 steps / s, so that the indoor combustible refrigerant can be transferred outward quickly, and the adverse effects of closing the valve too quickly on the intelligent air conditioner can be reduced. At the same time, the processor controls the internal fan to operate at a high windshield, and controls the external fan to operate at a high windshield, and then controls the compressor to operate at a high frequency of 66Hz to speed up the transfer speed of the combustible refrigerant as much as possible. In addition, in order to ensure the safety of the intelligent air conditioner when executing the refrigerant transfer plan, the processor continuously detects the real-time working current of the intelligent air conditioner. If the real-time working current at a high frequency of 66Hz is greater than the target frequency-limiting current of 11A, it indicates that there may be certain safety issues when the intelligent air conditioner executes the refrigerant transfer plan in this state. Therefore, the processor reduces the operating frequency of the compressor at a speed of 0.33Hz / s and updates the real-time working current of the intelligent air conditioner. When it is detected that the new real-time working current is less than or equal to the target frequency-limiting current of 11A, the compressor no longer performs the frequency reduction operation, and the intelligent air conditioner continues to operate at the operating frequency at this time. After 80 seconds, the flammable refrigerant stored in the smart air conditioner has been basically discharged to the outside, and the processor controls the compressor, the inner fan and the outer fan to shut down together, and the smart air conditioner is powered off. Therefore, this embodiment can complete the transfer of the flammable refrigerant in the room before the indoor danger expands, thereby assisting the smart air conditioner to avoid secondary damage in time, which is conducive to ensuring the safety of users at home.

[0057] Combination Figure 3 As shown, the embodiment of the present disclosure provides another method for controlling a smart air conditioner, comprising:

[0058] S301, the processor responds to the control instruction of the safety linkage mode and determines the risk warning level of the smart air conditioner according to the safety linkage mode.

[0059] S302: When the risk warning level of the smart air conditioner is a primary risk warning, the processor determines that the risk response plan of the smart air conditioner is a power-off protection plan.

[0060] S303: When the risk warning level of the smart air conditioner is a medium risk warning, the processor determines that the risk response plan of the smart air conditioner is a refrigerant transfer plan.

[0061] S304, the processor controls the intelligent air conditioner to operate in cooling mode and controls the throttle valve to close.

[0062] S305, the processor controls the compressor, the indoor fan and the outdoor fan to run for a preset time and then shut down to transfer the refrigerant from the indoor side to the outdoor side.

[0063] S306: When the risk warning level of the smart air conditioner is a high-level risk warning, the processor determines that the risk response plan of the smart air conditioner is a refrigerant isolation plan.

[0064] According to the method for controlling the intelligent air conditioner provided by the embodiment of the present disclosure, when the intelligent air conditioner receives the control instruction of the safety linkage mode, the risk degree corresponding to the safety linkage mode is first analyzed, and then the risk warning level of the intelligent air conditioner is determined, and the risk response plan corresponding to the intelligent air conditioner is determined accordingly, so as to facilitate the control of the intelligent air conditioner to make adaptive adjustments to reasonably avoid risks. When the risk warning level is the primary risk warning, the risk response plan at this time is the power-off protection plan, which is conducive to avoiding subsequent risks by timely powering off the intelligent air conditioner. When the risk warning level is the intermediate risk warning, the risk response plan at this time is the refrigerant transfer plan, and the intelligent air conditioner operates in the cooling mode and closes the throttle valve to cut off the path of the flammable refrigerant flowing from the outdoor side to the indoor side. Subsequently, the compressor, the indoor fan and the outdoor fan are shut down after the preset time, so that the flammable refrigerant can be gradually transferred from the indoor side to the outdoor side through the refrigerant pipeline. Therefore, the embodiment of the present disclosure can discharge the flammable refrigerant stored in the indoor unit of the intelligent air conditioner to the outdoor side in advance when there is a safety hazard indoors, so as to assist the intelligent air conditioner to avoid secondary damage before the indoor danger expands, which is conducive to ensuring the safety of users at home. When the risk warning level is a high-level risk warning, the risk response plan at this time, the refrigerant isolation plan, can reduce the damage to the smart air conditioner by quickly isolating the indoor refrigerant from the outdoor refrigerant, which is conducive to avoiding further expansion of the dangerous situation.

[0065] Optionally, after the processor determines that the risk response plan of the smart air conditioner is a power-off protection plan, the process further includes: the processor controls the smart air conditioner to turn off the working power supply. In this way, the embodiment of the present disclosure can turn off the working power supply of the smart air conditioner to promptly power off the smart air conditioner, thereby facilitating the avoidance of subsequent risks.

[0066] Optionally, after the processor determines that the risk response plan of the smart air conditioner is a refrigerant isolation plan, the process further includes: the processor controls the throttle valve to close at a maximum valve closing rate. In this way, the disclosed embodiment can quickly close the throttle valve of the smart air conditioner to isolate the refrigerant in the internal unit from the refrigerant in the external unit as quickly as possible, thereby reducing the degree of damage to the smart air conditioner and preventing the danger from further expanding.

[0067] Combination Figure 4 As shown, the embodiment of the present disclosure provides another method for controlling a smart air conditioner, comprising:

[0068] S401: The processor determines a risk response plan for the smart air conditioner in response to a control instruction of the safety linkage mode.

[0069] S402, when the risk response plan is the refrigerant transfer plan, the processor controls the intelligent air conditioner to operate in cooling mode and controls the throttle valve to close.

[0070] S403, the processor controls the compressor, the indoor fan and the outdoor fan to run for a preset time and then shut down to transfer the refrigerant from the indoor side to the outdoor side.

[0071] S404, the processor responds to the release instruction of the safety linkage mode, controls the intelligent air conditioner to start the working power, and controls the throttle valve to fully open.

[0072] S405, the processor detects the current operating current of the smart air conditioner.

[0073] S406: The processor determines the refrigerant leakage status of the smart air conditioner according to the current operating current.

[0074] S407, when the refrigerant leakage status is that no refrigerant leakage has occurred, the processor controls the intelligent air conditioner to release the safety linkage mode.

[0075] S408, when the refrigerant leakage state is that refrigerant leakage occurs, the processor controls the intelligent air conditioner to maintain a safety linkage mode.

[0076] According to the method for controlling the smart air conditioner provided by the embodiment of the present disclosure, when the smart air conditioner receives the control instruction of the safety linkage mode, a specific risk response plan is first determined to control the smart air conditioner to make adaptive adjustments to reasonably avoid risks. When the risk response plan is the refrigerant transfer plan, the smart air conditioner operates in the cooling mode and closes the throttle valve to cut off the path of the flammable refrigerant flowing from the outdoor side to the indoor side. Then, the compressor, the indoor fan and the outdoor fan are shut down after running for a preset time, so that the flammable refrigerant can be gradually transferred from the indoor side to the outdoor side through the refrigerant pipeline. Therefore, the embodiment of the present disclosure can discharge the flammable refrigerant stored in the indoor unit of the smart air conditioner to the outdoor side in advance when there is a safety hazard indoors, so as to assist the smart air conditioner to avoid secondary damage before the indoor danger expands, which is conducive to ensuring the safety of users at home. In addition, when the smart air conditioner receives the release instruction of the safety linkage mode, it is judged that the indoor danger has been released at this time. The smart air conditioner starts the power supply to start the working power supply, and controls the throttle valve to perform the valve opening action until it is fully opened, so that the flammable refrigerant gradually flows back to the indoor side. The smart air conditioner then detects the current working current and determines whether its actual operating status is normal based on this, and then controls the smart air conditioner to complete the determination of the refrigerant leakage status before resetting the operation. When it is determined that no refrigerant leakage has occurred, the smart air conditioner releases the safety linkage mode, so that it can respond to user instructions for cooling, air supply or standby operation to ensure the user's experience. When it is determined that a refrigerant leakage has occurred, the smart air conditioner maintains the safety linkage mode and does not respond to the user's control instructions to avoid continuous leakage of flammable refrigerants causing indoor dangers again, which is beneficial to ensure the safety of users at home.

[0077] Optionally, the processor determines the refrigerant leakage state of the intelligent air conditioner according to the current working current, including: the processor determines the current operating frequency of the compressor, and determines the preset verification current corresponding to the current operating frequency; when the current working current is greater than or equal to the preset verification current, the processor determines that the refrigerant leakage state is that no refrigerant leakage occurs; or, when the current working current is less than the preset verification current, the processor determines that the refrigerant leakage state is that refrigerant leakage occurs. In this way, the embodiment of the present disclosure can determine the corresponding preset verification current in combination with the current operating frequency of the compressor to assist in the determination of the refrigerant leakage state. If the current working current is greater than or equal to the preset verification current, it indicates that the actual operating state of the intelligent air conditioner at this time is relatively normal, and it does not have the problem of too low working current due to abnormal load, so the intelligent air conditioner determines that no refrigerant leakage has occurred at this time. If the current working current is less than the preset verification current, the working current of the intelligent air conditioner is too low at this time, which is most likely caused by the abnormal load caused by too little refrigerant circulation, so the intelligent air conditioner determines that a refrigerant leakage phenomenon has occurred at this time.

[0078] Optionally, the processor determines the preset calibration current corresponding to the current operating frequency, including: the processor determines the rated working current corresponding to the smart air conditioner according to the current operating frequency; the processor calculates the product of the rated working current and the calibration coefficient to obtain the preset calibration current. In this way, the embodiment of the present disclosure can determine the rated working current of the smart air conditioner when it operates normally according to the current operating frequency, and multiply it by the calibration coefficient on the basis of the rated working current, so as to obtain the corresponding preset calibration current, so as to reasonably judge whether the actual operating state of the smart air conditioner is normal, which is conducive to indirectly completing the determination of the refrigerant leakage state.

[0079] Optionally, the verification coefficient is less than 1. Preferably, the verification coefficient can be set to 0.6. The verification coefficient can also be adjusted according to the duration of the safety linkage mode to fully consider the difficulty of resetting the intelligent air conditioner, and can also be set to any other reasonable value such as 0.5 or 0.8.

[0080] Optionally, when the refrigerant leakage state is that a refrigerant leakage occurs, after the processor controls the smart air conditioner to maintain the safety linkage mode, the process further includes: the processor sends an alarm message to prompt the smart air conditioner that a refrigerant leakage occurs. In this way, if the smart air conditioner first identifies a refrigerant leakage phenomenon before resetting the operation, the embodiment of the present disclosure maintains the safety linkage mode and also sends an alarm message to remind the user, thereby assisting the user to eliminate the fault in time, which is conducive to improving the safety of the smart air conditioner.

[0081] Specifically, in some embodiments, the processor responds to the release instruction of the safety linkage mode and determines that the indoor danger has been released at this time. The smart air conditioner starts the working power supply and controls the throttle valve to perform the valve opening action at a speed of 5 steps / s until the throttle valve is fully opened, so that the flammable refrigerant stored on the outdoor side can gradually flow back to the indoor side, so as to facilitate the reset operation of the smart air conditioner. At the same time, the processor controls the indoor fan to run at a low windshield and controls the outdoor fan to run at a high windshield, and then controls the compressor to increase the frequency to the first operating frequency of 40Hz at a speed of 0.5Hz / s, and keep running. The first operating frequency of 40Hz corresponds to the rated working current of 2.6A in the normal mode of the smart air conditioner. Then, the calibration coefficient of 0.6 is introduced, and the processor determines that the preset calibration current corresponding to the first operating frequency of 40Hz is 1.56A. Then the processor detects the current working current of the smart air conditioner and compares it with the preset calibration current of 1.56A, so that the refrigerant leakage state can be determined before the smart air conditioner is reset, and the safety of the reset operation is further improved. If the current working current is less than the preset verification current of 1.56A, the working current is too low at this time, which is most likely caused by abnormal load due to too little refrigerant circulation. Therefore, the processor can determine that the smart air conditioner has a refrigerant leakage phenomenon at this time. In order to avoid possible system misjudgment, the processor can add another refrigerant leakage judgment process, and control the compressor to increase the frequency to the second operating frequency of 50Hz at a speed of 0.5Hz / s, and then keep running. The rated working current corresponding to the second operating frequency of 50Hz is 4.2A, and then multiplied by the verification coefficient of 0.6, the processor determines that the preset verification current corresponding to the second operating frequency of 50Hz is 2.52A. At this time, the processor updates the current working current of the smart air conditioner, and then compares it with the new preset verification current of 2.52A, so as to further improve the reliability of the refrigerant leakage phenomenon judgment. If the updated current working current is greater than or equal to the new preset verification current of 2.52A, it indicates that the actual operating state of the smart air conditioner at this time is relatively normal, and it does not have the problem of too low working current due to abnormal load. Therefore, the processor determines that the smart air conditioner has not yet had a refrigerant leakage phenomenon. The smart air conditioner is then controlled to release the safety linkage mode, so that it can respond to user instructions for cooling, air supply or standby operation to ensure the user's experience. If the updated current working current is still less than the new preset verification current of 2.52A, the working current is too low at this time, which is most likely caused by abnormal load due to insufficient refrigerant circulation. Therefore, the processor determines that the smart air conditioner has a refrigerant leakage at this time. Therefore, the processor controls the smart air conditioner to maintain the safety linkage mode so that it does not respond to the user's control instructions, thereby avoiding the continuous leakage of flammable refrigerant and causing indoor danger again, which is beneficial to ensure the user's home safety. At the same time, the processor sends an alarm message indicating refrigerant leakage to the user's terminal device to remind the user to eliminate the fault in time, which is beneficial to improve the safety of the smart air conditioner.
